JAMES STALLINGS, OF FAIRMOUNT, ILLINOIS.

SPRING-WHEEL.

To all whom it may concern:

Be it known, that I, JAMES STALLINGS, a citizen of the United States,residing at Fairmount, in the county of Vermilion and State of Illinois,have invented certain new and useful Improvements in Spring-VVheels, anddo hereby declare that the following is a full, clear, and exactdescription of the same, reference being had to the annexed drawings,making a part of this specification, and to the letters and figures ofreference marked thereon.

The increased cost of rubber and certain practical objections to the useof rubber for pneumatic and other yielding tires for automobiles andother vehicles, render desirable a cushion tire for automobiles andother vehicles having all the elasticity and other good qualities of thepneumatic tire without the drawbacks due to the employment of rubber andair, and the object of my invention, therefore, is to provide a cushiontire possessing the required elasticity, and yet economical ofconstruction, durable and of ready application to automobile and othervehicle wheels, and to this end my invention consists in the cushionedwheel constructed substantially as hereinafter specified and claimed.

I11 the accompanying drawingFigure 1 is a side elevation or wheelequipped with a tire embodying my invention, a portion of the inclosingcasing being removed to show the interior construction; Fig. 2 a topplan view thereof; and Figs. 3 and 4 are detail views of the outercasing parts.

In embodying my invention in a practical form, I employ a circularseries of crescent shaped springs 10, each formed of two leaf springmembers 0 joined at their ends and at each extremity having an eye 11.The eye-carrying extremities of adjacent springs 10, are spaced apartand a clevis a pivoted in each eye is attached to one end of a coilspring 7 that yieldingly draws the ends of adjacent springs 10 towardeach other and yieldingly maintains them in proper position so that itwill be seen that I provide a circular series of crescent shaped springs10, and coil springs alternating with each other. The concave side ofeach spring 10 is inward and it is firmly attached as by bolts f to theconvex side of a crescent shaped block 9, having near each end radialholes a Specification of Letters Patent.

Application filed July 20, 1910.

Patented Oct. 11, 1910.

Serial No. 572,933.

for the passage of bolts by means of which the crescent shaped block maybe attached to the felly or rim of a wheel 12. The crescent shapedblocks 9 while forming a simple means of attachment of the device to thefelly or rim of the wheel without any change in the wheel rim or felly,affords a solid and firm support for the springs while permitting allmovement that may be required to aiford the desired cushioning effect.

Inclosing the series of springs and their attaching blocks 9 is acircular shell or casing composed of two side members it and 7c, themember h having a circumferential rim or flange that forms a tread andto which the outer member of each crescent shaped spring 10 is fixed orsecured as by bolts or screws passing through small holes d in the outerleaf spring 0. The side plates h and is are secured together by bolts 71which pass through spacing or separator tubes Z.

It will be evident that by my invention I provide a spring wheel whichcombines with the necessary stiffness or rigidity required forautomobiles and other vehicles, all necessary cushioning capacity, andwhich possesses such strength as to render it not liable to injury, sothat it is durable.

It is understood that there are details of construction in theembodiment of my invention illustrated which I have described, which maybe varied from without involving any departure from the scope of myinvention.

What I claim is As an improvement in automobile and other vehiclewheels, the combination of a circular series of crescent shaped and coilsprin s in alternate arrangement, connections between the springs formedof engaging eyes and clevises, crescent shaped blocks at the concaveside of the crescent shaped springs, said blocks having means forattachment to a wheel rim or tire, a tire forming shell or casing havingside members, one of which has a circumferential rim or flange, andmeans connecting said rim or flange to said crescent shaped spring.

In testimony whereof I aflix my signature in presence of two witnesses.

JAMES STALLINGS.
